Loads of little bits of hardening off the failed pinion bearing are
likely to have caused some wear in the support bearings.

Are you sure - running in straight line the pinion bearing should have
been static and not causing you any problem at all.

I'm trying to get my head around this now, all my experience is saying
that's not right.. For instance my IIa with shortened prop and be heard well
busy in a straight ling with the FWH engadged. Disengaged and obviously it's
shtum... It's no where near shtum when engadged.

In fact it's got to be wrong otherwise how would you drive the wheels?????

Depends which pinion bearings.

If your talking about the hypoid pinion, those obviously runs all the
time.

If your talking about the bearings in the two bevel pinions which
actually form the guts of the diff, they only spin when the drive
shafts are rotating at different speeds. When straight ahead, those
bevel pinions whirl around but do not spin on their own shafts.

Any clearer?

"Confused?"

those are planet wheels though. Pinion is normally the bit where the drive
gets into the diff.

of course, in America, they probably have different names for all of the
bits.

Well at least I'm less confused, the pinion I'm dealing with is the one
which has the prop flange fastened to it. Now I'm not going to have to get
my technical lego kit off the top shelf and do a demo am I ;-)

Oh I love photographs... it's so much simpler... just too busy to scratch my
arse though at the mo... even this post is in passing the keyboard.

So the lump hammer is definately out the :-(

That's another good point (just to keep you occupied, Lee!) clean out
the axle housing as well as you can.

No probs... it's been flushed with EP90 already and will get a thrice over
before I'm done... something which I have in my DNA.. being fussey about
clealiness with mechanicals and motors in general...... Why have I got a 101
again? ;-)

I think that you and Lee are talking different pinion bearings!

Lee I'm pretty sure is talking about the pinion which is part of the
bevel gear and pinion set which which rotates whenever the propshaft
is turning.

It is true that the pinions in the diff. core do not rotate when
travelling in a straight line. Not that it there is a separate bearing
here (someone will correct me if I'm wrong) the diff. core pinions run
directly on the spider/crosshaft.

No I'm just having an incredibly blonde moment - too little sleep and

Right, Minor progress today, collected the Pinion and bevel gear from the
local engineers, they have given it a clean bill of health and pressed on
the new bearing.

I got the old bearing seat OD reduced 2 thou too while I was there for
mocking up the pinion height to make sure the shims are right to save
unecessary beating of the new bearing seat.. Once I know the pinion height
is correct with the right amount of shims I'll fit the new seat in place.
Should be right but I'm not taking any chances.

Off to a local blacksmiths tomorrow with a design for a spreader, most of it
I can build myself but material and holes (big'uns for the bolts to bolt it
together in the corners) I'm short of.

For any one still reading and learning spreaders look like this...

from the looks of it, I could make it for about 20 quid tops. for that
money I'd expect a dial gauge built-in...

As daft as it is, what choice do people have if they haven't the tools?It's
the only thing keeping Morph off the road at present, even if I were fool
enough to buy the one in the linked add it would still be cheaper than
cartingit off to Legs not that there quote was unreasonable given the work.

Thats the only one I could find.

Supply and Demand, they Supply it at that price and I've demanded a load of
bits ready to weld up which are now sat in the garage. Just need the bolts.

Nope it's not a feature mine has.

I understand Craddocks were doing the crown and pinion relatively cheap. So
whats going in there then... tru track?
